Star Marine! (The Fighter Queen saga Book 4)

Rated "R".

When the Sirian Confederacy attacked the Federation, six star systems became embroiled in a 22-year galactic war. Six years after the attack, the Federation is finally ready to go on the offensive. The plan - retake the Outer Worlds, liberate Altair and Alpha Centauri, then slam it down the enemy’s throat, invading Beta Centauri, Vega 3, and Sirius.

It takes all kinds to fight a war:

Rico Martinez: he locks and loads in the deadly bloodbath of Periscope Harbor.

Regina Wells: Can she learn the identity of the spy in time to save the Star Marines at Periscope Harbor?

Wade Palmer: Is there any way he can rescue the plan before the Star Marines are slaughtered?
